  • Patent number: 11818621
    Abstract: Handling of listen before talk (LBT) failures during radio resource control (RRC) procedures is disclosed. A user equipment (UE) may be configured to monitor for consistent uplink and downlink LBT failures on a bandwidth part (BWP) configured for a target cell. When the UE determines that consistent LBT failures are occurring with respect to the BWP, the UE may determine an LBT failure state on the BWP. In response, the UE may execute a recovery procedure, which may include selecting a new BWP associated with the target cell and having configured uplink resources, performing a cell reselection procedure, or switching to idle in order to perform cell selection. The UE may then report the LBT failures according to cell identification and BWP.

  • Patent number: 11792750
    Abstract: Aspects of the disclosure relate to a wireless user equipment (UE) establishing and utilizing a reference timing for a carrier or cell with multiple transmission and reception points (TRPs). A UE may receive a downlink signal on each of a plurality of component carriers (CCs), and determine respective timing events (e.g., slot boundaries, subframe boundaries, etc.) corresponding to each of the plurality of CCs. The UE may then determine a reference time for a first CC of the plurality of CCs. This reference time corresponds to a function of two or more timing events corresponding to different TRPs utilizing the first CC. The UE then determines a relative timing difference between the plurality of CCs based on this determined reference time. Other aspects, embodiments, and features are also claimed and described, including determining and utilizing a reference time on an uplink CC.

  • Patent number: 11706726
    Abstract: Methods, systems, and devices for dynamic monitoring modes for synchronization signal block (SSB) transmissions are described. A user equipment (UE) may monitor one or more first SSB transmission opportunities for SSB transmissions from a base station and determine an SSB failure rate. Based on the failure rate, the UE may select a mode for monitoring one or more second SSB transmission opportunities. For example, if the failure rate is greater than a threshold, the UE may select a first mode for monitoring a first quantity of the one or more second SSB transmission opportunities. Additionally, if the failure rate is less than the threshold, the UE may select a second mode for monitoring a second quantity different than the first quantity of the one or more second SSB transmission opportunities. The UE may monitor the one or more second SSB transmission opportunities according to the selected mode for monitoring.
